CARRIER-CLAMP FOR FlRE-ENGINE HOSE.

O SPECIFICATION forming part of Letters Patent No. 448,458, dated March 17, 1891.

' Application filed December 15, 1890. Serial No. 374,821. (No model.)

T all whom it may concern:

Be it known that I, THOMAS H. SAUNDERS, of Boston, in the county of Suffolk, State of Massaeh usetts, haveinvented certain new and useful Improvements in Carrier-Clamps for Fire-Engine Hose,of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to IO make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a sectional elevation showing my improved clamp in use on a ladder; Fig. 2, a top plan view of the clamp detached from the hose and locked by the pin, and Fig. 3 a similar view showing the clamp partially open.

Like letters of reference indicate correzo sponding parts in the different figures of the drawings.

My invention relates especially to a clamp adapted to be attached to fire-engine hose for the purpose of transporting the hose when in use and supporting; it upon the rungs of a fire-ladder; and it consists in certain novel features hereinafter fully set forth and claimed, the obj ectbeing to produce a simpler, cheaper, and more effective device of this character than is now in ordinary use.

The nature and operation of the improvement will be readily understood by all conversant With such matters from the following explanation.

In the drawings, A represents the hose 3 B, the ladder, and O the clamp, considered as a whole. The clamp is circular in form and is slightly less in diameter than the hose A when unfilled with water. The clamp O is formed in two sections 1) (Z hinged together by an end at f. A clamp-lever g is hinged at t; in the end of the section b opposite the hingef. A laterally-projecting stud h is formed on the free end of said lever. The corresponding end of the clamp-section (Z is provided with a laterallyprojecting hookshaped boss it", adapted to receive the stud h on the lever g, said boss being grooved at m to receive said lever when the clamp is closed. A pin-hole 5o 19 passes through the hook 7c, and a similar hole q is formed in the lever g in position to register with said holes 19 when the clamp is closed. A pin 0" is secured by a chain tto the section b and is fitted to enter said pin-holes.

.A loop '2) is formed on the section b and a strap D is secured in said loop, said strap serving as a handle for the fireman to carry the clamp and as a means for attaching it to his belt when not in use. A vertically-arranged laterally-projecting hook H is formed centrally on the section cZ-opposite the loop c, said hook being adapted to encircle the rung of a fire-ladder and support the clamp, as shown in Fig. 1.

In the use of my improvement, the clam psections being opened, it may readily be disposed around the hose. The locking-lever 9 being thrown down into the groove on of the opposite section, the pin ris inserted in the pinholes qand the clamp thus securely fixed to the hose. By means of the strap D the hose may now be transported as desired. Vihile mounting the ladder B by means of the hook II, the fireman is enabled to support the weight of the hose on the ladder-rungs. As soon as Water is turned onto the hose the pin 0- is withdrawn from the pin-holes p q, the hose being extended by the pressure of water, the sections (Z I) begin to separate, the studs h on the lever g are engaged by the hook 70 on the section Z) and the clamp securely locked on the hose. The length of the lever g permits the clamp to open ,sufficiently to allow for the expansion of the hose from the pressure of water.

Having thus explained my invention, what I claim is 1. A carrier-clamp for fire-engine hose, eomprising two sections hinged together and adapted to encircle the hose, a locking-lever hinged to the end of one section and provided with pin-holes adapted to register with pinholes in the opposite section, a stud on said lever, and hooks on said opposite section adapted to engage said stud, substantially as described.

2. In a carrier-clamp for fire-engine hose, the clamp 0, comprising the hinged sections 1) d, the section cl being provided with the hook is, pin-holes p, and groove m, in combi- IOC nation with the lever g, pivoted to the see tion I) and provided with the stud h and pinhole q, the chain t, and pin 0". arranged to 0perate substantially as set forth.

3. A carrier-clamp for fire-engine hose, comprisingtwo hinged sections adapted to encirole the hose, one of said sections being provided with a pivoted lever adapted to take on a hook on the opposite section and lock said sections together when the hose is expanded, 10

and a pin fitted to enter pin-holes in said hook-section and lever to secure said sections together when the hose is empty, substantia-lly as described.
